I would get a good assortment of tips and practice, practice, practice. I have tried the small torches and the pistol grip torches and they just don't feel comfortable to me. Others find them very comfortable to use. It's all in how comfortable you feel using one.

Fatigue is caused mostly from mounting or fitting with NVH's (Noise, Vibration and Harshness)levels. That's why they build out of plastic.

I'd like to think that i put my welds through quite a vibration test going through shrink dies, getting hit with a high crown mallet, and several rounds through the planisher, that they would hold up on any car or bike I build. If i was dealing with aircraft and something where body panels were structural, i's take proper care. But, that being said, many modern aircraft have TIG welds all over them.

It may not actually be a rote choice as much one of choosing the best technology at hand, provided enough familiarity with the tech varieties is to be had ...... maybe? Sometimes I choose stick-arc over MIG or TIG. ..... and the welds slide right by the sharp eyes in the neighborhood ..... And sometimes I have to argue with the welder over his choice of MIG when I am thinking TIG (4130 chromoly - ......... don't get me started on MIG over torch or TIG for 4130 air frames ... )

i have to say as a beginner welder of alloy .. tig is way easier to get a reasonable weld from doesn't seem to penetrate as well as gas but much easier
now just need a few hundred hours of practice on the oxy ..

TIG vs O/A debate aside, Harris 85 is a nice "medium sized" torch body. Use with the D-85 low equal/pressure mixer, set of tips, you're set. Harris tip sizes are -very- close to Meco tips #1-4, btw. So Meco tip/metal/thickness suggestions apply for panel work.
Low, equal pressure, pre-mix, correct tip size/profile (clean gas)= all you need. Harris 85 knobs are at the base, so you can hold it comfortably like a big pencil (or TIG torch). Bigger torch body also helps with the coffee jitters. Rick W.
